Actually, I've been hearing that the Excelerator coils are made in Germany by Detech. They seem to be pretty highly regarded when used on Whites detectors. In fact, I've read many posts where they claim a significant increase in both depth & coverage. The fact that they're sold by K'co doesn't mean they're automatically garbage; if that were the case, they also sell Minelab, Fisher, Garrett, etc. hmmm. Granted, they do seem to engage in some unsavory business practices (they sell LRL's to the gullible), but they do sell a whole whack of stuff and can get those volume sales for a company that wants to get a foothold in the N. American market. Even well established companies will do special deals with them (Garrett, Whites, Discovery). ...Willy.
